Patent number: 12186831Abstract: The present application provides a welding assembly and a battery module. The welding assembly includes: a first weldment; and a second weldment, welded and fixed with the first weldment to form a welding seam; where, at least one side of the welding seam is provided with an exhaust channel; and the exhaust channel is located between the first weldment and the second weldment. In the present application, an exhaust gas generated during welding can be discharged from the exhaust channel to prevent it from entering the welding seam to reduce the strength of the welding seam.Type: GrantFiled: July 29, 2021Date of Patent: January 7, 2025Assignee: CONTEMPORARY AMPEREX TECHNOLOGY (HONG KONG) LIMITEDInventors: Guofeng Liu, Anwei Wu, Xing Wang, Lei Wang, Bin Zhao, Linshan Wu

Publication number: 20240198362Abstract: The present application relates to a gluing nozzle and a gluing device. The gluing nozzle comprises an inner lined glue nozzle and an outer glue nozzle, wherein the inner lined glue nozzle comprises at least two sub-linings, and the at least two sub-linings are detachably connected and enclosed to form a glue cavity with a glue outlet; and the outer glue nozzle is detachably arranged on an outer side of the inner lined glue nozzle, such that the at least two sub-linings are relatively fixed. The gluing nozzle can solve the current problem that the production cost is increased since frequent replacement of a new glue discharging nozzle is required to ensure the uniformity of glue discharging.Type: ApplicationFiled: February 27, 2024Publication date: June 20, 2024Inventors: Laijuan Yu, Anwei Wu

Publication number: 20240097267Abstract: This application provides a battery and an electric device. The battery provided in this application is provided with a blocking member between two adjacent rows of battery cells along the length direction of the battery cell. In the process of assembling the battery cells in the box, the adhesive at the bottom of the battery cell, when spreading under compressing from the gap created by the housing chamfers to the end cover, will be blocked by the blocking member, thus preventing the adhesive from overflowing to the end cover, improving the safety performance of the battery.Type: ApplicationFiled: November 22, 2023Publication date: March 21, 2024Applicant: CONTEMPORARY AMPEREX TECHNOLOGY CO., LIMITEDInventors: Laijuan YU, Xingdi Chen, Ning Zhang, Anwei Wu, Ye Xu, Renyu Chen
